Astrometric measurements are used by astrophysicists to constrain certain models in celestial mechanics. By measuring the velocities of pulsars, it is possible to put a limit on the asymmetry of supernova explosions. Also, astrometric results are used to determine the distribution of dark matter in the galaxy. The method of astrometric measurements by Gaia is described from first principles, and the fundamental limitations explained in terms of physics (diffraction and photon noise), geometry, temporal sampling and reference frames.

Focal plane, containing the detector for the Astrometric instrument in light blue, Blue Photometer in dark blue, Red Photometer in red, and Radial Velocity Spectrometer in pink. Mirrors M4 and M'4, which combine the two incoming beams of light; Mirror M5; Mirror M6, which illuminates the focal plane

How is all this possible? The answer is: by a combination of many factors, the most important being bigger and more efficient detectors, and bigger optics. The The astrometric instrument returns data that allows scientists to measure the image centroids in order to measure the relative separation of the thousands of stars simultaneously present in the combined field of view. The instrument operates at a high angular resolution. IV. Astrometric calibration V. Search for moving objects VI. How to measure the position of the object VII.
